FOLDING BRACKET.

SPECIFICATION forming part of Letters Patent No. 511,626, dated December26, 1893.

Application filed May 10, 1893.

State of Massachusetts, have invented an Improvement in FoldingBrackets, of which the following description, in connection with theaccompanying drawings, is a specification,

' like letters on the drawings representing like parts.

This invention has for its object to improve the construction of foldingwall brackets for shelves and the like, and consists in details ofconstruction to be hereinafter pointed out.

Figure 1, shows in front elevation my improved wall bracket, secured toa wall and supporting the shelf; Fig. 2, a front View of the bracketfolded, and removed from the wall and shelf; Fig. 3, a left hand edgeview of the folding bracket shown in Fig. 2; and Fig. 4, a detailshowing an under side view of the sole plate.

The wall plate a, composed of a narrow strip of metal having countersunkholes through it for the attaching screws, has two forwardly projectingears 0, a, at its upper end with a narrow space between them. The soleor shelf supporting plate b likewise composed of a narrow strip of metalhaving countersunk holes through it for the attaching screws, has at itsrear end an ear 1), whichenters the narrow space between the cars a, a,on the wall plate. A suitable pivot pin passes through said ears a, a,1), thereby pivotally connecting or hinging the sole to the wall plate.In

lieu of this particular form of pivotal connection any other suitableform may be employed. The wall plate has also two projections a (1adjacent its upper and lower ends respectively, provided with holes orsockets, and the rib c is provided with pintles or projections whichenter said holes or sockets in the pro- Serial No. 473,664. (No model.)

jections a a thereby pivotally connecting said rib to the wall plate.The upper end of the rib at or near its frontend has a flat surfacedprojection c upon which the sole or shelf supporting plate bears whensaid rib is brought into alignment with said sole.

A spring cl of fiat metal is secured to the under side of the sole byapin cl or otherwise, the outer end of which is adapted to bear upon oragainst the under side of the shelf, and its central raised portionlying in the path of movement of the flat surfaced projection 0 on therib, while the pin d projects sufficiently to serve as an obstruction orabutment against which said projection 0 strikes, when the rib is swunginto line with the Wall plate, the sole passing over or by the spring.The

spring and pin thereby constitute a looking or retaining device for therib.

We claim- In a folding bracket, the combination of the wall plate a, thesole b hinged to the upper end of said Wttllplate, and adapted to folddown upon and in parallelism with the wall plate, socketed projections(t a on said wall plate, the rib 0 having pintles entering said sockets,and also having a flat surfaced projection c and spring d shaped asshown, secured to the sole 6, and the projecting pin d, which securesthe spring to the sole 1) and also serves as a limiting stop for theprojection 0 substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
